IMPROVED SCREW-PEG FOR BOOTS AND SHOES.

Specicaticn forming part of Letters Patent No. 85,374, dated December29, 1868.

To all whom it may concern:

Be it known that I, J. M. EsTABRooK, of Milford, in the county ofWorcester and State of Massachusetts, have invented a new and ImprovedScrew-Peg for Boots and Shoes; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, referencebeing had to the accompanying drawings, forming a part of thisspecification.

Figure l is a perspective view of my improved boot and shoe peg, andFig.' 2 is a side view of the same applied.

Similar letters of reference indicate corresponding parts.

The object of this invention is to facilitate the attachment of soles tothe uppers of boots and shoes; and consists in the construction of ascrew-peg having a flattened wedge-shaped point, which, when the peg isdriven into the sole of a boot or shoe, will strike against the metalplate upon the last and bend over the inner sole to form a clinch.

A in the drawing represents a screw-peg, made of round or other wire,which is provided with a screw-thread and a flattened wedgeshaped point,and is applied as follows: After the boot or shoe has been properlylasted, the holes for the pegs are made, by means of awls or otherwise,the requisite distances apart, and then the pegs are, point inward,forced in by means ofhammers or other equivalent instruments. Thewedge-pointed peg will, when it strikes the metal-covered last, have itsweak point bent down, and will therefore be properly clinched over theinsole.

I am fully aware that screws have already been used on boots and shoesfor fastening the soles to the uppers; but these screws were screwedinto their seats. They were of conical shape, and could never besatisfactorily fastened. When one of these screws was turned a littletoo far, so that its flat point struck the last, it would invariablytend to force the sole off the last again, and thus a real water-tightboot or shoe could not be produced. Furthermore, these screws had to bemade tapering, and thus became weak on their inner ends, while my pegscan be made entirely cylindrical or prisrnatic.

The process of screwing them in was very tedious, and still more-so thatof cutting them off the main wire, as no great accuracy could beobtained. l

I have invented the driving ot' screw-pegs having flattened orwedge-shaped ends into the leather by means of a hammer, and have foundthat the peg, when thus applied, will hold as fast as when screwed in.

The leather, being wet when the peg is applied, will close tight aroundthe peg, and will hold the same very Securely.

The clinching wedge-shaped pegs are selfadj ustable--that is, they willbe clinched more or less as they are more or less too long.

It is clearly evident that, by my improved process, much time and laborwill be saved. When the hole is properly prepared even a flat-ended pegcan be forced in by a hammer.

I am aware that cylindrical metallic screwpegs have been made with anexterior Screwthread; but this I do not claim.

`Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The self-clinchingmetallic screw-peg A, having a flattenedwedgashapedend, whereby, as it strikes the metal plate upon the last in the act ofdriving, it is adapted to be bent down into the inner sole of a boot orshoe, as herein shown and described.
